摘要：

A new species of Parotocinclus is described from the Rio Tocantins basin, Tocantins State, Brazil. The new species is distinguished from congeners by a combination of characters such as: (1) a unique pattern of body coloration with five transverse dark bars; (2) absence of an adipose fin or small platelet at typical adipose-fin region; (3) absence of conspicuous dark dots broadly distributed on the body; (4) absence of a triangular dark blotch at the anterior base of the dorsal fin; and (5) presence of a V-shaped spinelet.
